This tests linker script behavior, that gold distinguishes correctly
|
|
between
|
|
*(.x1) *(.x2) *(.x3)
|
|
and
|
|
*(.x1 .x2 .x3)
|
|
in an input section spec. In the first case, the output section
|
|
should contain all .x1 sections, followed by all .x2 sections,
|
|
then all .x3 sections; i.e.:
|
|
script_test_12a.o(.x1)
|
|
script_test_12b.o(.x1)
|
|
script_test_12a.o(.x2)
|
|
script_test_12b.o(.x2)
|
|
script_test_12a.o(.x3)
|
|
script_test_12b.o(.x3)
|
|
|
|
In the second case, the output section should interleave the
|
|
.x1, .x2, and .x3 sections in the order seen; i.e.:
|
|
script_test_12a.o(.x1)
|
|
script_test_12a.o(.x2)
|
|
script_test_12a.o(.x3)
|
|
script_test_12b.o(.x1)
|
|
script_test_12b.o(.x2)
|
|
script_test_12b.o(.x3)
|
|
|
|
The linker scripts set the absolute symbol INTERLEAVED, which we
|
|
test here to determine which ordering to expect. The scripts also
|
|
define the symbols test_array_start and test_array_end.
